Spinning display devices h'ave'heretofore been-proposed but have been complicated and relativelyheavy in-construction and expensive to manufacture and in most instances requiring an air heating source to induce the spinning action.

The device comprising the presentinven'tion comprises a simple one-piece circular blank which is so ;-provided with linesof sevarance, fold linesand integral-locking tabs, that the device may be stamped in a single operation, and may be simply set up and firmly held in set-up position, the device being characterized primarily by its simplicity and lightness of weight.

As a further feature of the device the simplicity of construction contributes such lightness of weight to the device that it needs no artificial agent for moving air therethrough, such as, heaters, fans or the like, but will spin rapidly and most attractively by normally induced convection currents which may occur adjacent a wall which is of a temperature different from that of the ambient air.

Other features of the invention will be more apparent from the accompanying drawing and following detailed description.

In the drawing,

Fig. l is a top plan view of the spinner in set-up position.

Fig. 2 is an elevational view of the device illustrated in Fig. 1.

Fig. 3 is a bottom plan view of the device.

Fig. 4 is an enlarged detailed sectional view taken on line 44 of Fig. 2.

Fig. 5 is a development of the blank from which the spinner shown 'in Figs. 1, 2 and 3 is formed.

Referring particularly to the drawings and with specific reference to Fig. 5, 1 indicates a relatively flat blank pref erably circular in peripheral contour and constructed of cardboard, sheet plastic or like foldable, resilient sheet material. The blank 1 is severed along a plurality of arcuate lines 2, 3 and 4, the centers of curvature of the lines each being eccentric with respect to the center of the blank and each lying on the arc of a circle which is concentric with the center of the blank.

The line of severance 2 extends from the periphery of the blank and terminates inwardly of the blank in a pair of fold lines 5 and 6 which, with the line of severance 4, defines a triangular segment 7. In similar fashion line 3 terminates inwardly of the blank and joins fold lines 8 and 9 which, with severance line 2, defines triangular segment 10. In similar fashion line 4 joins fold lines 11 and 12 to define triangular segment 13. Lines of severance 2, 3 and 4, together with fold lines 6, 9 and 12, define a central substantially triangular segment 14 at substantially the central portion of the blank 1.

d States Patent In addition, line of severance 2 with fold line 5, a portion of severance line 4 and a portion of the periphery of the blank, define a fragmentary crescent-shaped portion 15. In similar fashion, severance line 3, fold line 8, a portion of severance line 2 and a portion of the periphcry of the blank define a second fragmentary crescentshaped portion 16 and a third fragmentary crescent-shaped portion 17 is defined by severance line 4, fold line 11, a portion of severance line 3 and the remaining portion of the blank periphery.

As will be hereinafter described, the fragmentary crescent-shaped portions 15, 16 and 17, when the device is set up, provide'wings upon which moving air is adapted to impinge, and said portions will hereinafter be referred to as wing sections 15, 16 and 17, respectively.

Wing-section 15, at arcuately spaced portions thereof, is severed alongsemicircular lines to provide relatively small arcuately-shaped tongues 18 and 1?. In similar fashion, wing section 16 carries arcuately spaced tongues 20 and 21, and wing section 17 carries tongues 22 and 23.

In setting up the device, the sharply pointed portion of wing 17 is moved beneath the blunt portion of a wing section-15 and tongue 23 is engaged with tongue 18, as shown best in Figs. 2 and 4. In similar fashion, the sharply pointed portion of wing'section 15 is moved beneath the blunt portion of wing section 16, and tongues 19 and 2f) are interengaged. Similarly, the sharply pointed portion of wing-section 16 is moved beneath the blunt portion of wing section 17 and tongues 21 and 22 are interengaged.

The periphery of the blank 1 is thus contracted and the respective wing sections are arcuately warped. The respective fold lines 5 and 6, 8 and 9, and 11 and 12, facilitate the warping of the wing sections and facilitate the merging of the wing sections with the relatively flat central portion 14 which now becomes a top of the display.

A hearing member 24 of metal or other hard, rigid material is inserted in a central aperture provided in the top 14, the lower portion of the member carrying a flange 25 having a central recess 26 (Fig. 3) which forms a bearing for an upright rod or support 27, the upper end of which loosely seats in the recess 26. Thus the set-up device is rotatably carried by the rod 27.

The wing sections 15, 16 and 17 are all angularly inclined in the same direction, and, in effect, constitute air scoops. Thus, air moving upwardly from the bottom of the device through the openings 28 (Fig. 2) at the top of the device, exert a force upon the wing sections which tend to rotate the display.

Of course, the outer faces of the wing sections can be suitably printed or decorated to provide an advertising message and to lend attractiveness to the display, The tongues 18 to 23 are shown as being semicircular in shape, but it is to be understood that any suitable shape tongues are contemplated. If desired, the tongues 18 to 23 may be replaced by rivets or adhesive spots or any other suitable attaching means.

By virtue of the simplicity of the present device, the device is extremely light and can be rotated by a minimum of air movement, requiring no artificial air-moving mechanism such as a heater, a fan or an electric bulb from which heat is employed to establish a convection current. Of course, the present device can be used with such air-moving agencies but in most instances such agencies are not necessary. In addition, the device can be constructed in one operation; the periphery may be cut, the lines of severance cut and the lines of fold scored, all in one stamping operation.
